Referring to FIGS. 1 to 7, a vehicle 100 may include a plurality of wheels, which are rotated by a power source, and a steering input device 510 for controlling a driving direction of the vehicle 100.

The vehicle 100 may be an autonomous vehicle. The vehicle 100 may travel autonomously under the control of the controller 170. The vehicle 100 may travel autonomously based on vehicle driving information.

When the vehicle 100 enters a set distance from a preset destination or receives a stop request while travelling, the vehicle 100 may search for at least one available stopping area or a recommended area based on acquired vehicle driving information, and then display information about the found available stopping area or the recommended area on the display unit 251 or transmit such information to a terminal, e.g., a preset terminal. Detailed description thereof will be provided later with reference with FIG. 8 and following drawings.

The vehicle driving information may be information that is acquired using various units, provided in the vehicle 100, during travelling of the vehicle 100. The vehicle driving information may be information that is utilized by the controller 170 or the operation system 700 to control the vehicle 100.

For example, the vehicle driving information may include at least one of the following: object information acquired by the object detection device 300, information received by the communication device 400, and a user input received by the user interface device 200 or the driving manipulation device 500.

For example, object information may be information about a shape, a location, size, and color of an object detected by the object detection device 300. For example, object information may be information about a traffic line, an obstacle, a nearby vehicle, a pedestrian, a traffic light, a road structure, contents of a traffic sign plate, and the like.

For example, information received by the communication device 400 may be information transmitted by a device that is capable of performing communication. For example, information received by the communication device 400 may be information transmitted by a nearby vehicle, information transmitted by a mobile terminal, information transmitted by traffic infrastructure, and information existing in a specific network. The traffic infrastructure may include a traffic light, and the traffic light may transmit information about a traffic signal.

For example, vehicle driving information may include at least one of the following: navigation information, information on a control state of the vehicle 100, and location information of the vehicle 100. For example, the vehicle driving information may include: information on a nearby vehicle, which is transmitted by the nearby vehicle itself: information on a travel path of the vehicle 100: and map information.

For example, the vehicle driving information may indicate: a type, location, and movement of an object existing around the vehicle 100; whether a traffic line exists in the vicinity of the vehicle 100; whether any nearby vehicle is travelling while the vehicle 100 is stopped; whether there is a space for the vehicle to stop in the vicinity; a probability of collision between the vehicle 100 and an object; where a pedestrian or a bicycle is located with reference to the vehicle 100; type of a road on which the vehicle 100 is travelling, a status of a traffic light in the vicinity of the vehicle 100, and movement of the vehicle 100.

The vehicle driving information may be acquired using at least one of the user interface device 200, the object detection device 300, the communication device 400, the driving manipulation device 500, the navigation system 770, the sensing unit 120, the interface 130, and the memory 140, and then provided to the controller 170. Based on the vehicle driving information, the controller 170 may control the vehicle 100 to travel autonomously.

A control mode of the vehicle 100 may be a mode indicating of which subject controls the vehicle 100. For example, the control mode of the vehicle 100 may include: an autonomous vehicle in which the control unit 170 or the operation system 700 included in the vehicle 100 controls the vehicle 100; a manual mode in which a driver in the vehicle 100 controls the vehicle 100; and a remote control mode in which a different device other than the vehicle 100 controls the vehicle 100.

When the vehicle 100 is in the autonomous mode, the controller 170 or the operation system 700 may control the vehicle 100 based on vehicle driving information. Accordingly, the vehicle 100 may travel without a user command received using the driving manipulation device 500. For example, the vehicle 100 in the autonomous mode may travel based on information, data, or a signal that is generated in a driving system 710, a parking-out system 740, and a parking system 750.

When the vehicle 100 in the manual mode, the vehicle 100 may be controlled by a user command received using the driving manipulation device 500, the user command which is with regard to at least one of steering, acceleration, and deceleration. In this case, the driving manipulation device 500 may generate an input signal corresponding to the user command, and provide the generated input signal to the controller 170. The controller 170 may control the vehicle based on the input signal provided by the driving manipulation device 500.

When the vehicle 100 in the remote control mode, a different device other than the vehicle 100 may control the vehicle 100. If the vehicle 100 operates in the remote control mode, the vehicle 100 may receive a remote control signal, transmitted by a nearby vehicle, through the communication device 400. The vehicle 100 may be controlled based on the remote control signal.

Based on a user input received using the user interface device 200, the vehicle 100 may enter one of the autonomous mode, the manual mode, and the remote control mode. A control mode of the vehicle 100 may be switched to one of the autonomous mode, the manual mode, and the remote control mode based on at least one of driver state information, vehicle driving information, and vehicle state information.

For example, the control mode of the vehicle 100 may be switched from a manual mode to an autonomous mode, or vice versa, based on object information generated by the object detection device 300. For example, the control mode of the vehicle 100 may be switched from a manual mode to an autonomous mode, or vice versa, based on information received using the communication device 400.

The occupant information may include an image or biometric information of a driver, which is sensed using the internal camera 220 or the biometric sensing unit 230. For example, occupant information may be an image about an occupant's location, shape, gaze, face, behavior, and facial expression, the image which is acquired using the internal camera 220. For example, biometric information may be information about an occupant's temperature, heart rate, and brainwaves, the image which is acquired using the biometric sensing unit 230. For example, occupant information may indicate a location of an occupant, gaze direction thereof, a health condition thereof, and an emotional state thereof, and whether the occupant is dozing off or not. Occupant information may be acquired using an occupant detection unit 240 and then provided to the controller 170.

The vehicle state information may be information about the states of various units provided in the vehicle 100. For example, the vehicle state information may include information about the operational states of the user interface device 200, the object detection device 300, the communication device 400, the driving manipulation device 500, the vehicle drive device 600, and the operation system 700, and information about an error of each unit. For example, the vehicle state information may indicate: whether a GPS signal of the vehicle 100 is received normally; whether an error has occurred in at least one sensor provided in the vehicle 100, and whether each device provided in the vehicle 100 operates normally.

For example, the term “overall length” means the length from the front end to the rear end of the vehicle 100, the term “overall width” means the width of the vehicle 100, and the term “overall height” means the height from the bottom of the wheel to the roof. In the following description, the term “overall length direction L” may mean the reference direction for the measurement of the overall length of the vehicle 100, the term “overall width direction W” may mean the reference direction for the measurement of the overall width of the vehicle 100, and the term “overall height direction H” may mean the reference direction for the measurement of the overall height of the vehicle 100.

When the vehicle 100 enters a set distance from a preset destination or receives a stop request while travelling, the controller 170 may search for at least one available stopping area based on acquired vehicle driving information, and then display information about the found available stopping area on the display unit 251 or transmit such information to a preset terminal.

FIG. 8 illustrates an example method for controlling a vehicle.

While the vehicle 100 travels in S100, the controller 170 may determine whether the vehicle 100 enters a set distance from a preset destination or receives a stop request in S200.

While the vehicle 100 travels, the controller 170 may acquire vehicle driving information using at least one of the user interface device 200, the object detection device 300, the communication device 400, the driving manipulation device 500, the navigation system 770, the sensing unit 120, the interface 130, and the memory 140.

Based on destination information and location information of the vehicle 100, the controller 170 may determine whether the vehicle 100 enters a set distance from a preset destination. The set distance may be a value stored in the memory 140 and may be set by the user.

The controller 170 may sense a user command, received in the user interface device 200 or the communication device 400, to determine whether a stop request has been received.

When the vehicle enters the set distance from the preset destination or the stop request is received, the controller 170 may search for at least one available stopping area based on acquired vehicle driving information in S300.

An available stopping area indicates an area of a certain width where the vehicle 100 can to stop. At least one available stopping area may or may not exist. When there are two or more available stopping areas, each of them may have different size, location, and shape. The fact that there is no available stopping area means that there is no area for the vehicle 100 to stop in the vicinity.

The preset terminal 10 may be a user's terminal. In this case, a top view image showing the found available stopping area 1000 may be displayed on the screen of the terminal 10. The user is able to check the found available stopping area 1000 or direct the vehicle 100 to stop at a specific location even when the user is not inside the vehicle 100.

Referring to FIG. 9B, the controller 170 may display a found available stopping area 1000 in augmented reality (AR) using an HUD or the transparent display 251 c implemented in the windshield. In this case, the user is able to see a specific mark 1000 shown in an available stopping area.

Hereinafter, detailed description about a case where the controller 170 determines an available stopping area will be provided with reference to FIGS. 10 to 13.

Based on object information provided from the object detection device 300, the controller 170 may determine that an area where a parking or stopping-allowed line exists on a roadway on which the vehicle 100 is now travelling is an available stopping area.

FIG. 10 illustrates example parking lines and example stopping-allowed lines.

In some implementations, the parking lines or the stopping-allowed lines can be lines on a road. In some other implementations, the parking lines or the stopping-allowed lines can be color curbs. A type or color of a line may indicate a degree of allowance of parking or stopping a vehicle according to regulations. For example, a broken yellow line 1000 d on the side of the roadway may be a line that allows stopping for less than 5 minutes. A solid white line 1000 c on the side of the roadway may be a line that allows parking or stopping anytime. A solid yellow line 1000 a on the side of the road may be a line that allows stopping on an hourly basis or a day-of-week basis. Double yellow lines may be lines that prohibit parking or stopping. Each country or region may have different regulations on the types and colors of lines.

The object includes a traffic line. A signal or information provided by the object detection device 300 to the controller 170 may be referred to as object information. The object information is included in vehicle driving information.

Based on object information included in vehicle driving information, the controller 170 may determine a type, a location, and color of a traffic line existing in the vicinity of the vehicle 100. For example, based on object information, the controller 170 may distinguish a broken line and a solid line, distinguish color of a line, and determine a location of each line.

In some implementations, the controller 170 may determine that an area where the broken yellow line 1000 d or the solid white line 1000 c exists on the road is an available stopping area. However, if a stop period of the vehicle 100 is set in advance to less than 5 minutes, the controller 170 may determine that an area where only the solid white line 1000 c exists is an available stopping area. If the broken yellow line 1000 a is detected and it is determined that hours during which the vehicle 100 will be stopped corresponds to stopping allowed hours of the solid yellow line 1000 a, the controller 170 may determine that an area outlined by the solid yellow line 1000 a is an available stopping area.

In some other implementations, based on object information provided by the object detection device 300, the controller 170 may determine that an area having a space for the vehicle 100 to enter and stop is an available stopping area.

The object detection device 300 may detect an object existing within a specific distance from the vehicle 100. The object may include an obstacle, a nearby vehicle, a pedestrian, and any other object of certain volume. Based on the object information, the controller 170 may detect an object existing around the vehicle 100. The controller 170 may determine volume of a space that exists in a specific area.

Based on object information, the controller 170 may determine whether there is a space large enough for the vehicle 100 to stop. If it is determined, based on the object information, that there is a space for the vehicle 100 to enter and stop, the controller 170 may determine that an area having such a space is an available stopping area.

FIG. 11 illustrates an example vehicle that determines whether a particular area is an available stopping area.

In the example illustrated in FIG. 11, based on object information, the controller 170 may determine that an area in which a parking or stopping-allowed line exists, no other object is present, and there is a space for the vehicle 100 to enter and stop is an available stopping area 1100 a.

For example, the parking or stopping-allowed line may be a broken yellow line 1000 d and a solid white line 1000 c.

Based on object information, the controller 170 may determine that an area 1100 a in which no other object is present in the entire area outlined by the broken yellow line 1000 d and which has a space for the vehicle 100 to stop is an available stopping area. Based on the object information, the controller 170 may determine that an area 1100 b is not an available stopping area despite the broken yellow line 1000 d on the left side of the roadway, because an object is present in the area 1100 b.

Based on the object information, the controller 170 may determine that there is the solid white line 1000 c on the right side of the roadway. The controller 170 may determine that an area 1100 a in which no other object is present in the entire area outlined by the solid white line 1000 c and which has a space for the vehicle 100 to stop is an available stopping area. The controller 170 may determine that the area 1100 b in the area outlined by the solid white line 1000 c is not an available stopping area, because a nearby vehicle is present in the area 1100 b and thus the vehicle 100 is not allowed to enter.

Based on the object information, the controller 170 may determine that there is double solid yellow lines 1000 b on the left side of the roadway. The controller 170 may determine that an area outlined by the double solid yellow lines 1000 b is not an available stopping area.

FIG. 12 illustrates an example vehicle that determines whether a particular area is not an available stopping area.

In the example illustrated in FIG. 12, based on information received through the communication device 400, the controller 170 may determine that an area 1200 already assigned to a nearby vehicle 101 to stop is not an available stopping area.

Using the communication device 400, the controller 170 may receive information transmitted by a different device. The different device may include a nearby vehicle, a mobile terminal, and a server.

Using the communication device 400, the controller 170 may receive information transmitted by the nearby vehicle 101. The nearby vehicle 101 may select an area desired to stop, and information on the selected area 1200. The information on the selected area 1200 may include information on a location of the selected area 1200.

If the information on the selected area 1200, transmitted by the nearby vehicle 101, is received, the controller 170 may determine that the area 1200 is an area already assigned to the nearby vehicle 101 to stop. The controller 170 may determine that the area already assigned to the nearby vehicle 101 to stop is not an available stopping area.

FIGS. 13A to 13C illustrate another example vehicle that determines whether a particular area is not an available stopping area.

In the examples illustrated in FIGS. 13A to 13C, based on at least one of object information, map information, and regulation information, the controller 170 may determine that an area within a legal distance from an illegal stopping area, a bus stop, a taxi stand, a subway station, a train station, an intersection, a ramp, a traffic structure, an access road, or two or more thereof is not an available stopping area.

Vehicle driving information may include object information, map information, and regulation information. The map information may include map images provided by the navigation system 770. The map information may include information about a type/shape/width of a road, a traffic light, a crosswalk, a footbridge, an underground passageway, a stop, and any other road infrastructure or structure. The regulation information may be information on regulations on parking or stopping of a vehicle. The regulation information may be updated through the network.

For example, based on at least one of object information, map information, and regulation information, the controller 170 may determine that a specific area determined to be an illegal stopping area is not an available stopping area. The illegal stopping area may include an area existing within a legal distance from any one among a bus stop, a taxi stand, a subway station, a train station, an intersection, a ramp, a traffic structure, an access road. The legal distance may be determined based on the regulation information or may be set by a user.

FIGS. 13A to 13C are diagrams for explanation of a case where an autonomous vehicle according to the present invention determines that an illegal stopping area is not an available stopping area.

Referring to FIG. 13A, based on object information or map information, the controller 170 may determine that a crosswalk 1301 c exists within a specific distance from the vehicle 100. Based on regulation information, the controller 170 may determine that an area 1301 b within a legal distance from the crosswalk 1301 c is not an available stopping area. For example, the controller 170 may determine that an area having 10 meter from the crosswalk 1301 c is not an available stopping area.

Except the area 1301 b within the legal distance from the crosswalk 1301 c, the controller 170 may determine that the area 1301 a on the both sides of the roadway is an available stopping area.

Referring to FIG. 13B, based on object information or map information, the controller 170 may sense an intersection. Based on regulation information, the controller 170 may determine that an area 1302 b within a legal distance from the intersection is not an available stopping area. A number of vehicles make turns to the right or the left at the intersection, so, if a vehicle is stopped at the intersection, it will block vision of other vehicles.

The controller 170 may determine that areas 1302 d and 1302 e within a legal distance from a subway station 1303 or a bus stop 1304 are not available stopping areas. The controller 170 may determine that an area 1303 c existing within a legal distance from an access road is not an available stopping area.

The controller 170 may determine that an area 1302 a on the side of the roadway is an available stopping area, except the areas 1302 b, 1302 c, 1302 d, and 1302 e which are determined not to be an available stopping area.

Referring to FIG. 13C, if it is determined, based on at least one of object information, map information, and regulation information, that an area is allowed between certain hours, the controller 170 may determine that the area is an available stopping area only during the parking allowed hours.

For example, based on object information, the controller 170 may sense a traffic sign plate 1330 indicating stopping allowed hours, and determine contents of the traffic sign plate 1330. For example, if a solid yellow line allows stopping between certain hours and the traffic sign plate 1330 indicates that stopping is allowed between 11:00 and 15:00, the controller 170 may determine that an area outlined by the solid yellow line is an available stopping area between 11:00 and 15:00.

Referring to (a) of FIG. 13C, if the current time is within stopping allowed hours, the controller 170 may determine that an area outlined by a solid line is an available stopping area 1100 a. For example, if stopping allowed time hours are between 11:00 and 15:00 and the current time is 12:00, the controller 170 may determine that an area outlined by a solid line is the available stopping area 1100 a. Even in such a case, if a pre-input scheduled time period of the vehicle 100 indicates that the vehicle 100 will remain stopped even after 15:00, the controller 170 may determine that the area outlined by the solid line is not an available stopping area.

Referring to (b) of FIG. 13C, if the current time is not within stopping allowed hours, the controller 170 may determine that an area outlined by a solid line is an unavailable stopping area 1100 b. For example, if a legal time allowed for stopping is between 11:00 and 15:00 and the current time is 10:00, the controller 170 may determine that an area outlined by a solid line is the unavailable stopping area 1100 b. In such a case, the controller 170 may display, on the display unit 251 provided inside the vehicle 100, a message notifying that stopping will be allowed in one hour.

FIG. 14 illustrates an example vehicle that determines whether a particular area is a recommended area among one or more available stopping areas.

In the example illustrated in FIG. 14, based on vehicle driving information, the controller 170 may determine a recommended area in a found available stopping area. The controller 170 may display information about the recommended area on the display unit 251 or transmit such information a preset terminal.

A recommended area 1400 may be part of an available stopping area 1100 a. The recommended area 1400 may be an area where parking the vehicle 100 is relatively advantageous.

For example, the recommended area 1400 may be an area which the vehicle 100 can arrive at the earliest time in an available stopping area, an area closest to a destination, an area from which a user can reach a destination at the earliest time, an area which is most safe, or an area which fits a user's desired stopping type.

The controller 170 may determine not just an available stopping area but a recommended area, and display information about the recommended area through the display unit 251 or a terminal, thereby helping a user to decide where to stop the vehicle 100. In this case, the user may select the recommended area or a different space in the available stopping area.

At last, the controller 170 may control the vehicle 100 to stop at a point selected by the user. If the vehicle drive device 600 provided in the vehicle 100 operates in accordance with a control signal of the controller 170, the vehicle 100 may move to a selected stopping location and stop there.

FIGS. 15 to 20 illustrate example vehicles that determines whether a particular area is a recommended area.

FIG. 15 illustrates an example vehicle that determines whether a particular area is a recommended area that is the closest to a destination by a distance.

Based on map information, the controller 170 may determine that an area 1400, in which the vehicle 100 is able to stop as close as possible to a preset destination 1500 within a found available stopping area 1100 a, is a recommended area.

Based on map information included in vehicle driving information, the controller 170 may determine a location of an area which is closest to the preset destination 1500 within the available stopping area 1100 a.

In this case, the recommended area 1400 is a space within the available stopping area 1100 a, which is at the closest distance to the preset distance 1500, and therefore, it is possible to reduce a distance that a user needs to walk from the destination 1500 to the vehicle 100 or from the vehicle 100 to the destination 1500.

The controller 170 may display, on the display unit 251, the recommended area 1400 closest to the preset destination 1500. If a user input which selects the recommended area 1400 is received through the user interface device 300, the controller 170 may control the vehicle to move to the recommended area 1400. In this case, the vehicle 100 may move to the recommended area 1400 by going straight and then making a U-turn.

If a user selects a different area other than the recommended area 1400 in the available stopping area 1100 a, the controller 170 may control the vehicle 100 to stop at the selected area.

FIG. 16 illustrates an example vehicle that determines whether a particular area is a recommended area that is the closest to a destination by time.

Based on at least one of map information, traffic information, and location information, the controller 170 may determine that an area having the smallest sum of a first time and a second time within the found available stopping area 1100 a is a recommended area. The first time is a time required for the vehicle 100 to completely stop in the found available stopping area 1100 a, and the second time is a time required for a user to reach a destination 1500 from a location at which the vehicle 100 is stopped.

In a case where the vehicle 100 plans to stop at a point closest to a destination in the available stopping area 1100 a, if it takes a long time for the vehicle 100 to reach the point, a user is better to get off the vehicle 100 and walk to the destination in order to arrive there more quickly. In such a case, the autonomous vehicle 100 according to the present invention determines that a point having the smallest sum of the first time, required for the vehicle 100 to reach a desired stopping location, and the second time, required for a user to get off the vehicle 100 and walk to the destination 1500, is a recommended area, and therefore, it is possible to reduce the time for the user to reach the destination 1500.

The controller 170 may calculate the first time, which is required for the vehicle 100 to reach each point in the available stopping area 1100 a, based on map information, traffic information, and location information.

The traffic information may include signal information of a traffic light and information about a real-time amount of traffic. The traffic information may be information received from a server that provides real-time traffic information. Accordingly, the more number of vehicles around the available stopping area 1100 a, the longer the first time can be.

Based on traffic information, the controller 170 may determine a signal transition time of a traffic light. Based on an amount of traffic and the signal transition time of the traffic light, the controller 170 may determine the first time.

The controller 170 may calculate the second time, which is required for a user to reach the destination 1500 from a location at which the vehicle 100 will stop, based on map information, traffic information, and location information.

Based on map information, the controller 170 may determine a path and a distance, which are required for the user to move to the destination 1500 by foot.

Based on traffic information, the controller 170 may determine a signal transition time of a pedestrian signal. If a user disembarks at a certain location to walk across a crosswalk, the controller 170 may determine, based on the signal transition time of the pedestrian signal, a time required for the user to walk across the crosswalk. If a user disembarks in an available stopping area on the right side of the roadway, the controller 170 may calculate a second time by taking into account how long it takes for the user to walk across a crosswalk.

For example, if there are a huge amount of traffic or it takes a long time until a signal is changed, a user may be better to walk to a destination by foot, rather than driving the vehicle 100 to a point closest to the destination. The controller 170 may calculate a sum of the first time and the second time in the case (a) where the vehicle 100 moves to an available stopping area closest to the destination 1500, and a sum of the first time and the second time in the case (b) where the vehicle 100 moves to an available stopping area 1400 closest to a crosswalk, and then the controller 170 may compare the results. If it is determined that the sum of the first time and the second time of the case (b) is smaller than that of the case (a), the controller 170 may determine that the available stopping area 1400 closest to the crosswalk is a recommended area.

FIG. 17 illustrates an example vehicle that determines whether a particular area is a recommended area based on a safety level.

The controller 170 may calculate safety level distribution in a found available stopping area 1100 a based on object information, nearby vehicle information, and traffic information. The nearby vehicle information may be information transmitted by a nearby vehicle. The nearby vehicle information may include information about a location, a speed, a control status, a model, and an occupant of the nearby vehicle.

To calculate a safety level, the controller 170 may set at least one expected stopping location 1700 within the found available stopping area 1100 a.

According to the width of the found available stopping area 1100 a and the size of the vehicle, the controller 170 may determine a location of each expected stopping location 1700 and the number of expected stopping locations 1700. By calculating a safety level of each of the multiple expected stopping locations 1700, the controller 170 may calculate safety level distribution in the available stopping area 1100 a.

A safety level may be a value indicating how much a corresponding area is safe. For example, an area having a relatively high safety level may be determined to be safer than an area having a relatively low safety level. A safety level may indicate a probability of the vehicle 100 to collide with a nearby vehicle while moving to a desired stopping area and an amount of traffic within a specific distance from the desired stopping area. For example, if the vehicle 100 is highly likely to collide with a nearby vehicle when moving to a desired stopping area, a safety level may be low. In another example, if there is a huge amount of traffic within a specific distance from the desired stopping area, it may result in a high probability of collision between the vehicle 100 and a nearby vehicle or the vehicle 100 may block vision or path of the nearby vehicle, and therefore, a safety level may be low.

To calculate a safety level, the controller 170 may perform, based on object information or nearby vehicle information, simulation of a case where the vehicle 100 moves to at least one expected stopping location 1700. The controller 170 may determine that a safety level is in inverse proportion to a probability of collision between the vehicle 100 and a nearby vehicle calculated through simulation. Accordingly, the controller 170 may determine that a lower safety level will be obtained if a higher collision probability is calculated through simulation.

To calculate a safety level, the controller 170 may determine, based on traffic information, that an amount of traffic within a set distance from at least one expected stopping location 1700 is in inverse proportion to a safety level of the expected stopping location 1700. The set distance may be a value determined through experiments. For example, the set distance may be a distance to a lane adjacent to an expected stopping location. The set distance may be a value set by a user.

In some implementations, based on at least one of object information, nearby vehicle information, and traffic information, the controller 170 may determine that a relatively greater number of vehicles exits in lanes on the right side of the roadway than those on the left side. The greater number of vehicles on the road means that the vehicle 100 is highly likely to collide with a nearby vehicle and that there is a huge amount of traffic in the vicinity of the vehicle 100. Thus, the controller 170 may determine that a safety level corresponding to expected stopping locations 1700 on the left side of the roadway is higher than a safety level corresponding to expected stopping locations 1700 on the right side. Accordingly, the controller 170 may determine that an available stopping area which corresponds to the expected stopping locations 1700 on the left side of the roadway is a recommended point 1400.

The controller 170 may determine that an area having a safety level equal to or greater than a set value in a found available stopping area 1100 a is the recommended area 1400. The set value may be a value determined through experiments or may be set by a user. If there is no area having a safety level equal to or greater than a set value in the found available stopping area 1100 a, the controller 170 may determine that an area having the highest safety level in the found available stopping area 1100 a is the recommended area 1400.

FIG. 18 illustrates an example vehicle that determines whether a particular area is a recommended area based on an expected stop duration.

The controller 170 may determine an expected stop duration of the vehicle 100 based on stopping type information. Based on object information, the controller 170 may determine that an area corresponding to the expected stop duration of the vehicle 100 in a found available stopping area is a recommended area.

The stopping type information may be information that indicates a pre-input expected stop duration of the vehicle 100. The expected stop duration may indicate a length of time for which the vehicle 100 is stopped at a specific destination. For example, before or while driving the vehicle 100, a user may input information indicating that the vehicle 100 will be stopped at the specific destination for 10 minutes. As the user's input with regard to the expected stop duration is received through the user interface device 200, the controller 170 may store stopping type information in the memory 140. Vehicle driving information may include the stopping type information.

An area corresponding to an expected stop duration of the vehicle 100 may be an area which allows stopping for the expected stop duration. For example, if an expected stop duration is 10 minutes, an area which allows stopping for 10 minutes or more may be an area corresponding to the expected stop duration.

In an example (a) in FIG. 18, the controller 170 may determine, based on stopping type information, that an expected stop duration of the vehicle 100 is less than 5 minutes. Based on object information, the controller 170 may determine an area which allows stopping for less than 5 minutes within a found available stopping area 1100 a. In a case where an area outlined by a solid white line 1000 c allows stopping without time limit and an area outlined by a broken yellow line 1000 b allows stopping for less than 5 minutes, each of the two areas may be an area corresponding to the expected stop duration of the vehicle 100. In this case, the controller 170 may determine that the entire available stopping area 1100 a is a recommended area 1400.

In an example (b) shown in FIG. 18, the controller 170 may determine, based on stopping type information, that an expected stop duration of the vehicle 100 is 10 minutes or more. Based on object information, the controller 170 may determine which area allows stopping for 10 minutes or more within a found available stopping area 1100 a. In a case where an area outlined by a solid white line 1000 c allows stopping without a time limit and an area outlined by a broken yellow line 1100 b allows stopping for less than 5 minutes, the area outlined by the solid white line 1000 c may be an area corresponding to an expected stop duration. In this case, the controller 170 may determine that an area outlined by the solid white line 1000 c in the found available stopping area 1100 a is a recommended area 1400.

FIG. 19 illustrates an example vehicle that determines whether a particular area is a recommended area based on a direction toward which the vehicle moves when the vehicle leaves the area for a destination.

When it is determined, based on destination information, that a destination 1500 b after stopping has been set, the controller 170 may determine, based on map information and destination information, that an area adjacent to a lane toward the destination 1500 b within the found available stopping area 1100 a is a recommended area 1400.

Two or more destinations of the vehicle 100 may be set. If two or more destinations of the vehicle 100 is set, the controller 170 may determine that there are one final destination and one or more waypoints. In this case, the vehicle 100 may reach one or more waypoints sequentially and then move to the final destination.

Information about the preset destination of the vehicle 100 may be destination information. For example, destination information may indicate a waypoint and a final destination. According to a user input with regard to a destination, received through the user interface device 200, the controller 170 may store destination information in the memory 140.

In the case where the vehicle 100 reaches a waypoint and is stopped there for a certain period of time, there may be a location at which it is convenient for the vehicle 100 to move to a next destination. For example, suppose that a first stopping location can be reached without making a U-turn, that a second stopping location can be reached by making a U-turn, and that a next destination is at a location that can be reached by making a U-turn. In this case, if the vehicle 100 is stopped at the first stopping location, it is necessary to make a U-turn to reach the next location. On the other hand, if the vehicle 100 is stopped at the second stopping location, it is not necessary to make an additional U-turn to reach the next destination. Thus, the second stopping location may be a location at which the vehicle 100 is able to relatively easily and conveniently move to the next destination.

In an example shown in FIG. 19, the controller 170 may determine, based on destination information, that a waypoint 1500 a and a next destination 1500 b are set. If it is determined that the destination 1500 b after stopping is set, the controller 170 may search, based on map information and destination information, for an area which is adjacent to a lane toward the destination 1500 b within a found available stopping area 1100 a. Based on the map information and the destination information, the controller 170 may determine that the area adjacent to a lane toward the destination 1500 b within the available stopping area 1100 a is an available stopping area present in a lane on the right side of the roadway. In this case, a user needs to move to the waypoint 1500 a or move from the waypoint 1500 a to the vehicle 100, and thus, the controller 170 may determine that an area closest to a crosswalk within the available stopping area 1100 a is a recommended area.

FIG. 20 illustrates an example vehicle that determines whether a particular area is a recommended area based on an occupant disembarking location.

The controller 170 may determine an occupant disembarking location based on occupant location information. For example, the occupant disembarking location represents a drop-off location at which an occupant of a vehicle gets off the vehicle.

The occupant location information is information that indicates a location of an occupant inside the vehicle 100. For example, the occupant location information may indicate that an occupant is located at a driver's seat or a right rear seat in the vehicle 100. Vehicle driving information may include the occupant location information. The controller 170 may acquire the occupant location information using the occupant sensing unit 240.

Based on the occupant location information, the controller 170 may determine an occupant disembarking location. For example, if an occupant is located at a right rear seat, the controller 170 may determine that an occupant disembarking location is on the right rear side.

In an example (a) shown in FIG. 20, the controller 170 may determine, based on occupant location information, that an occupant disembarking location is on the right rear side.

In an example (b) shown in FIG. 20, the controller 170 may determine, based on occupant location information, that an occupant disembarking location is on the left front side.

Based on object information, the controller 170 may determine that an area in a found available stopping area 1100 a in which any structure 2000 a or 200 b does not exists within a set disembarking distance from the occupant disembarking location is a recommended area 1400.

The set disembarking distance may be a distance that is required to disembark a passenger from the vehicle 100. For example, the set disembarking distance may be a distance that is required to fully open a door of the vehicle 100. The set disembarking distance may be determined through experiments or may be set by a user.

A structure may be a street tree, a traffic sign plate, an obstacle, a wall, and any other object of certain volume.

In an example (a) shown in FIG. 20, the controller 170 may determine, based on object information, an area 1400 in a found available stopping area 1100 a in which a street tree 2000 b or a traffic corn 2000 a does not exist within a set disembarking distance from the right rear occupant disembarking location. If an occupant disembarking location is on the right rear side and it is determined that the traffic corn 200 a exists within the set disembarking distance from the right rear occupant disembarking location, the controller 170 may determine that an area in which the vehicle 100 is now positioned is not a recommended area. If any structure does not exit around the right rear occupant disembarking location, the controller 170 may determine that an area where the vehicle 100 is not positioned is a recommended area 1400, although the street tree 2000 b is located on the right-side front of the vehicle 100. The controller 170 may determine that the area 1400 in the available stopping area 1100 a, in which the street tree 2000 b or the traffic corn 2000 a does not exist within the set disembarking distance from the right rear occupant disembarking location, is a recommended area.

In an example (b) shown in FIG. 20, the controller 170 may determine, based on object information, an area 1400 in the found available stopping area 1100 a in which the street tree 2000 b or the traffic corn 2000 a does not exists within a set disembarking distance from the left front occupant disembarking location. If an occupant disembarking location is on the left front side and any structure 2000 a or 200 b exists on the right side of the vehicle 100, the controller 170 may determine that any structure 2000 a or 2000 b does not exists within a set disembarking distance from the occupant disembarking location. Because a structure 2000 a or 2000 b is located on the right side of the available stopping area 1100 a and the occupant disembarking location is on the left side, the controller 170 may determine that the whole available stopping area 1100 a is a recommended area 1400.

FIG. 21 illustrates an example vehicle that stops at a particular location selected by a user.

If a user selection of a specific point in a found available stopping area 1000 is received, the controller 170 may control the vehicle 100 to stop at the specific point corresponding to the user selection.

The controller 170 may display the available stopping area 1000 in augmented reality (AR) through a transparent display implemented in the windshield 251 c or through an HUD.

The controller 170 may display, on the windshield 251 c, a notification 2100 b that the vehicle 100 will stop at a point selected by the user.

In response to reception of a user input which selects a specific point in the available stopping area 1000 displayed on the windshield, the controller 170 may control the vehicle 100 to stop at the specific point selected by the user. A specific point corresponding to the user's selection is the specific point selected by the user.

In this case, the input unit 210 of the user interface device 200 may be a device that receives a user input of touching the windshield 251 c.

The controller 170 may control the vehicle drive device 600 so that the vehicle 100 moves to a point corresponding to the user's selection.

FIG. 22 illustrates an example vehicle that transmits information about a stopping location.

Using the communication device 400, the controller 170 may transmit information on a point at which the vehicle 100 will stop.

In response to a user input that selects the specific point 2200 in an available stopping area 1100 a, the controller 170 may control the vehicle 100 to stop at a specific point 2200 which is selected according to the user input. If the point 2200 at which the vehicle 100 will stop is determined, the controller 170 may transmit information about the point 2200.

The information about the point 2200 may include information about a location of the point 2200 and information about a stop period of the vehicle 100.

The controller 170 may transmit information about the point 2200 in a broadcasting manner. In this case, a communication device within a specific distance from the vehicle 100 may receive the information about the point 2200.

FIG. 23 illustrates an example vehicle that provides a notification to a user in a state in which the vehicle is not allowed to stop at a specific point selected by the user.

If it is determined during travelling of the vehicle 100 to a specific point selected by a user, based on vehicle driving information, that the vehicle 100 is not allowed to stop at the specific point, the controller 170 may output a stopping menu 2300 b through the user interface device 200.
